1. Selected species. Peanut pods are first selected before sowing, and the fruit, rotten fruit and insect fruit are removed. Secondly, after peeling the rice, it is graded according to the size of the grain, and the seeds are sown together, the seeds are centered together, and the seeds with small, sputum, sprouting and mildew are eliminated.
　　 2. Sun seed before sowing. Before sowing, the fruit can kill the pathogen on the epidermis of the pod, enhance the water permeability of the seed coat, accelerate the water absorption process of the seed, promote the activity of the enzyme, facilitate the transformation of nutrients in the seed, increase the germination rate of the seed, and prepare the seedlings neatly. Seed maturity is poor and moisture is stored during storage, and the effect of drying is more significant. After sun-breeding, the peanuts can be produced 1 to 2 days earlier , which can increase yield by 10% to 15% . Choose a sunny morning, put the peanut fruit on the drying field, thickness 1~2 inches, continuous drying for 2~3 days, always flip, and evenly uniform.
　　 3. Peeling at night. Judging from the survey, many farmers have already stripped peanut seeds in advance. There are many unfavorable factors in doing so. First, the physiology of the peeled skin is accelerated, the breathing is accelerated, the nutrient consumption is increased, and the second is susceptible to mildew. Reduce the germination rate of the seeds; third, the seeds are easily peeled off after drying, resulting in an increase in the rate of seed breakage during sowing, reducing the practicability of the seeds, and it is difficult to ensure that the peanut seedlings are full of seedlings. Peeling is best done half a month before the peanuts are sowed.
　　 4. Chemical dressing. In recent years, peanut bacterial wilt, root rot, and stem rot have occurred. Many farmers do not know how to deal with it in advance, but wait until the disease occurs, and then start fighting drugs. In fact, the prevention and treatment is late, and the control effect is not satisfactory. Chemical dressing is a method with small investment and good control effect. Therefore, seeding must be seeded, seed dressing should be adapted to local conditions, do not blindly use drugs.
